Sirtuins = cellular longevity switches π§¬
These NAD+-dependent proteins:
β Repair DNA damage
β Boost mitochondrial health
β Regulate metabolism
β Enhance stress resistance
SIRT1-7 family = evolutionarily conserved across species
Key interventions:
β NAD+ precursors (NR/NMN)
β Caloric restriction
β Small molecule activators
The challenge? Moving from mouse models to validated human therapeutics.
